First off it's been over seven years, it's not hard to understand that black lives matter is a decentralized movement that is not centrally represented.
The website is not the movement.
Second, both of those "opinion pieces" have references to high profile black lives matter activists (deray, shaun king, etc) speaking out about Daniel Shaver, so that's about as official as you're going to get.
Third, that "facebook post" documents an actual event organized by the family of Daniel Shaver, thanking the local blm chapter for their support.
If you have a more substantial voice that has done more than blm in bringing attention to this issue in a productive way, feel free to bring that forward.
True, but it's been weaponized extremely well by one side in recent years (2012~14 and onwards). Reminds me a lot of how it was weaponized by the other side in the late 80s and 90s.
I honestly have no idea which “side” you mean. Seems to me that both mainstream political sides are mainly about victimhood now. The whole point of Trumpism is “actually I’m the victim”
I don't believe this is true. Can you like anything on BlackLivesMatter.com that touches on Daniel Shaver's death?
